You may not care much about polar bears, and I can understand that because who would want to be within clawing distance of such a mammoth creature. The problem is that the possible extinction of the polar bears connected to the melting of the polar ice caps, are all indicators of a looming catastrophe. What we are looking at is not only the disappearance of a species, but as well the disappearance of coastal cities as ocean levels rise. Here are some challenges that we need to place before government: does government promote accessible public transportation vs. an expansion of roads and cars; does government promote planned community development vs. the destruction of rural land and the building of homes everywhere imaginable; does government invest in alternative energy sources (e.g., ...

Melting Arctic ice may lead to interbreeding, extinction As the world heats up and polar ice melts, different types of bears, whales and seals could meet and mate -- but these unions may be far from happy, researchers say. In fact, interspecies sex could lead to the extinction of many endangered Arctic animals, the scientists said in an article published in the journal Nature.

Polar bears are cute. Just ask the marketing executives at Coca- Cola which used animated polar bears to hawk their wares in recent years. Bears, pandas, lions and elephants are "charismatic megafauna" meaning basically cute animals that people care about. If you want to sell a product, or a cause, just tie it to one of these animals and you've got the attention of millions of people; kids and adults alike. Thus, environmental alarmists have made much of research claiming the Arctic's great white bear faces extinction from human-caused global warming. Snails, snakes and spiders withering in the sun just don't pack the same emotional punch as a cuddly, furry polar bear slipping beneath the melting ice.

In one of the most dramatic signs ever documented of how shrinking Arctic sea ice impacts polar bears, researchers at the U.S. Geological Survey in Alaska have tracked a female bear that swam nine days across the deep, frigid Beaufort Sea before reaching an ice floe 426 miles offshore. The marathon swim came at a cost: With little food likely available once she arrived, the bear lost 22 percent of her body weight and her year-old female cub, who set off on the journey but did not survive, the researchers said.
